Yes, might be a pain in the ass though if you don't remember the password or username.Yeah I don't remember squat so it might end up being too much effort to go through. I don't even know what email I used for it.
https://classic.support.neopets.com/hc/en-us/requests/new is the support page for submitting requests in case you do remember some info but not everything. I'm waiting on a response from them now after not receiving any password recovery emails in two days :(
